eSims are fast, simple and you can activate your device without waiting for a physical SIM card. Plus, it's more secure and never stores any of your personal information. As there is no tiny SIM card to insert in your device, it's also much easier to use an eSIM. And you won't lose it, so no lost SIM cards to replace. The use of eSIM is environmentally friendly as it eliminates plastic SIM card waste.
